Untersuchungen der Wellenabsorption im Bereich der unteren Hybridresonanz an einem Plasma hoher Ionenmasse / Investigations of Wave Absorption Near the Lower Hybrid Resonance in a Plasma of High Ion Mass

Abstract

Abstract The propagation and absorption of waves in the vicinity of the lower hybrid resonance are investigated under linear conditions in a cesium plasma generated by a Q-machine. The results of the measurements are compared with linear theories based on the fluid model. It is shown that in the case of high ion mass plasma only a theory including a finite k||-spectrum yields an appropriate description of wave absorption near the lower hybrid resonance.
